Abstract
In the previous paper, the magnetic surface, V″ and the rotational transform angle of a wavy toroidal field with helical multipole are studied by analytecal approximation using a average method. In this paper these quanties are obtained by numerical computations and the results arrcompared with the analytical ones with good agreement. The case of 1=1 in this configuration is favorable to obtain larger rotational transform angle and it corn-es-ponds with a field of simple torus with off axis helical dipole field. The fatures of this confignrator are examined.
